Abstract: A seal bore protector for protecting a seal bore of a rotating control device (RCD) is provided. The seal bore protector includes a cylindrical body, a throughbore extending through the cylindrical body, and a sealing element disposed around an external surface of the cylindrical body. The sealing element includes a first sealing ring, a second sealing ring, and a sealed area between the first sealing ring and the second sealing ring. The sealed area is fluidly coupled with a port when the seal bore protector is installed in the rotating control device.

Abstract: A valve stem arrangement for use in an adjustable choke, the valve stem being configured to prevent damage to components of the adjustable choke during downstream overpressure conditions. The valve stem generally connects a valve gate to an actuator for moving the valve gate within the choke. A set of shear screws couple components of the valve stem together. During overpressure conditions, the shear screws shear, permitting retraction of the valve gate towards an open position, thereby relieving loads on various choke components.

Abstract: A well choke, and an actuation mechanism for the well choke are described. The actuation mechanism includes a linearly translating drive mechanism which is coupled to a valve member drive assembly through a fluid coupling which facilitates a change in the overall length of the actuation mechanism. Fluid in the fluid coupling can be released in response to fluid pressure exerted on the valve member when it is proximate a valve seat of the choke, to achieve this change in length. In some embodiments, the fluid coupling will provide a retained fluid column and the valve member drive assembly will include a piston with in the fluid coupling which is movable from a fully extended to a compressed, by the release of fluid from the coupling in response to pressure in the chamber reaching a threshold level.

Abstract: A rotating control device (RCD) sensor assembly is provided. The rotating control device sensor assembly includes an emitter disposed on a rotational component of a rotating control device, wherein the emitter emanates a detectable signal field, a cap coupled to the rotational component to form a volume between the cap and the rotational component, wherein the emitter is enclosed within the volume, and wherein the cap is made of a transmissive material, and a sensor that detects the signal field through the cap as the emitter passes within a proximity of the sensor.
